MacSales-- As a preamble to this history, I want you to know that I studied electrical engineering in college, and have been professionally developing software for 20+ years. I understand the electronic and software issues of flash at a fairly detailed level, including the method by which sandforce controllers compress data and arrange it in the flash address space, and such things as, for instance, the mechanism by which individual flash bits store data and degrade over time. To bring you up to speed, here's what's occurred so far: March 10, 2011: I bought an SSD (OWCDDMBSSD120) in order number [redacted] ~March 15, 2011: You ship the order April 4th, 2011: I receive the SSD (I'm in england, takes time for things to cross the pond and clear customs, but all told this is reasonably fast.) April 12th, 2011: I contact OWC Customer Service, get non-responsive response on 4/13. This is less than 30 days after you ship. April 13th, 2011: Request RMA [RMA-number] RMA Request-[RMA-request-number] because the drive does not work. If you will review your email, you will notice that I said the issue was intermittent, but often resulting in inability for computer to see the drive. April 13th, 2011: Request Refund after drive is returned, told that your "guarantee" is for 30 days after *order placed*, meaning you effectively only guaranteed drive for 9 days (or 26 days after you shipped.) April 14th, 2011: I attempt to discuss the issue with your CSR, but it becomes clear they can't help diagnose. April 16th, 2011: I returned the SSD April 25th, 2011: I received the *exact same* drive I RMA'd back from you. Apparently untouched (and dumped in the bottom of the box, so it shipped without any physical protection) hilariously, later your tries to snow me with BS about this. Here's the relevant quotes: "The box the drive was returned in had 5 sheets of foam. However, the drive was simply thrown in the box, and the 5 sheets of foam were put in on top of it. The Data Doubler was between the foam sheets, but the drive was not. If the box was knocked against a sharp object, or any object, the drive took the full force of the damage. Further, since it was just thrown in there it was not in its anti-static bag. I don't know how sensitive to static these things are, but I suspect there is a reason every manufacturer ships a drive in anti-static bags." "The foam inserts used are anti-static themselves; therefore do not require the SSDs to be sleeved in anti-static bags. These foam inserts eliminate the bags from being used with SSD drives, but still required with the conventional Hard Drives when being shipped. " But of course, the drive was not in the foam inserts. It was on the bottom, sitting next to a thin piece of cardboard that was the bottom of the box.... the bottom being, typically, the part that is slammed on shelves and truck floors when boxes are shipped. April 26th, 2011: Am told that "the SSD was not a failed SSD/defective SSD" April 28th, 2011: Attempting to determine why you claim the drive is not defective, I am met with: "no defects, or any other symptoms with this SSD that alerted us to test for any extended period of time. " -- so you didn't actually test the drive I sent back, with an *intermittent* failure because it worked immediately. "Our testing procedures, prognosis and/or repair protocols are propriety" So, you refuse to explain to me *why* you believe the drive was not defective, on a technical level. It is recommended that I use the drive for 2 weeks. I defer to this recommendation, against my better judgement, and use the drive. It lasts much longer than 2 weeks, in fact, it lasts all the way until October 28th, 2011. Then it failed again, taking a fair bit of work with it that occurred in the 24 hours since its last backup. Fortunately, I only lost a day, but that day is worth ten times the $279 the drive costs. So, in short: 1. You refused to honor your 30 day money back guarantee. 2. You returned the defective drive back to me. 3. I foolishly trusted you, even though on every occasion I was snowed with BS and dishonesty from your CSR. 4. The defective drive failed 6 months later. I'll be happy to return the drive again, but only for a refund,. I'm not expecting you to do the honorable thing now that the time limit for a chargeback on the credit card has expired. The moral of the story: I should have forced you to honor your guarantee by sending the drive back and disputing the charges on my credit card. One thing I can tell you is this: I won't be an OWC customer ever again, and I'm going to be letting others know about this incident. No longer a customer-- [signed my name] ------------------------------- In case anyone is thinking this is a stupid user problem on my part, I have Seagate FreeAgent GoFlex drives for my backup drive. The cables are essentially just an SATA connector. Its trivial to plug in bare drives to them to test. When I say the "drive failed", it failed. The internal Macbook Pro SATA connectors can't see it, and I can plug the drive into one of the FreeAgent cables any time I want, and have done so several times, including just now to verify. Disk Utility and the rest of Mac OS X cannot see the drive. This is, by the way, completely consistent with sand force controller failure. When these controllers fail, they don't physically fail, they simply paint themselves into a corner where they can't' write any more data or read any data, and so they don't respond to the computer attempting to see the drive (let alone mount it.) Flashing the controller, as they did when they got my drive back, resets the problem obviously, but didn't fix the defect. I believe the most likely defect here is a QC defect on one of he flash chips-- either it has a largish section of cells that don't work. Or I suspect it could be a defect in the DRAM the drive uses for temporary caching, which happens only rarely, but I lucked into by having it happen the first 9 days I had the product. ---------- I post this here because I regularly see people say "I've never heard anything bad about MacSales", and stuff like that. They had 3 opportunities to make this right, and they didn't even try.
